### Pseudodeterminants and perfect square spanning tree counts

- Mathematics
- 2013

The pseudodeterminant pdet(M) of a square matrix is the last nonzero coefficient in its characteristic polynomial; for a nonsingular matrix, this is just the determinant. If ∂ is a symmetric or…

### BARYCENTRIC CHARACTERISTIC NUMBERS

- Mathematics
- 2015

If G is the category of finite simple graphs G = (V,E), the linear space V of valuations on G has a basis given by the f-numbers vk(G) counting complete subgraphs Kk+1 in G. The barycentric…

### Green functions of Energized complexes

- MathematicsArXiv
- 2020

It is proved here that the quadratic energy expression summing over all pairs h(x)^* h(y) of intersecting sets is a signed sum of squares of Green function entries.

### A combinatorial expression for the group inverse of symmetric M-matrices

- MathematicsSpecial Matrices
- 2021

Abstract By using combinatorial techniques, we obtain an extension of the matrix-tree theorem for general symmetric M-matrices with no restrictions, this means that we do not have to assume the…

### Gauss-Bonnet for multi-linear valuations

- MathematicsArXiv
- 2016

We prove Gauss-Bonnet and Poincare-Hopf formulas for multi-linear valuations on finite simple graphs G=(V,E) and answer affirmatively a conjecture of Gruenbaum from 1970 by constructing higher order…

### The zeta function for circular graphs

- MathematicsArXiv
- 2013

It is proved that the roots of zeta(n,s) converge for n to infinity to the line Re(s)=1/2 in the sense that for every compact subset K in the complement of this line, and large enough n, no root of the zeta function zeta(-s) is in K.

### The Kuenneth formula for graphs

- MathematicsArXiv
- 2015

The Kuenneth identity is proven using Hodge describing the harmonic forms by the product f g of harmonic forms of G and H and uses a discrete de Rham theorem given by a combinatorial chain homotopy between simplicial and de Ram cohomology.

### The Tree-Forest Ratio

- MathematicsArXiv
- 2022

. The number of rooted spanning forests divided by the number of spanning rooted trees in a graph G with Kirchhoﬀ matrix K is the spectral quantity τ ( G ) = det(1 + K ) / det( K ) of G by the matrix…

### On the Coefficients of the Characteristic Polynomial

- Mathematics
- 1998

It is a well-known fact that the first and last non-trivial coefficients of the characteristic polynomial of a linear operator are respectively its trace and its determinant. This work shows how to…

### The McKean-Singer Formula in Graph Theory

- MathematicsArXiv
- 2013

The McKean-Singer formula chi(G) = str(exp(-t L)) which holds for any complex time t, and is proved to allow to find explicit pairs of non-isometric graphs which have isospectral Dirac operators.
